WIRELESS TIE INSULATOR.

Application filed November 18, 1919. Serial No. 338,846,

T all 20710712. it may coomemt:

Be it known that I, HARRY A. F RE ERIC a citizen of the United Chicora, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Wireless Tie Insulators, of which the following is a specification.

This invention relates to insulators, and a. primary object of the invention is to provide an improved insulator for telephones, telegraph or other wires which is so constructed as to eliminate the necessity of employing the usual tie or binding wire. r

A further object of the invention is the provision of an insulator formed of one piece of insulating material having animproved means for holding or looking a part of the line wire out of direct alignment with the main portion of the wire, whereby slipping of the wire in anydirection in relation to the insulator is prevented.

A further object of the invention is the provision of means of varying the distance in which the depression of. the wire may be moved out of alignment with the main portion of the wire, so that any slack occurring in the wire can be taken up.

.\ still further object of the inventionis the provision of an improved means for moving the portion of the wire which is desired to he (lepressed to locking position. so as to permit the easy and ready placing of the wire in locked position on. the insulator.v

still further object of the'invention is the provision of an improved insulator constructed of a single piece of insulating material, which owing to the novel construction thereof is capable of supporting one'or more line wires. y

A still further object of the invention is.

the provision of an approved insulator of the above character which is durable and efficient in use, one which is simple and easy to nnuiufacture, undone which can beplaced upon the market at a reasonable cost.

Other objects will appear in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, and in which drawl igure 'l :is a front elevation of the 1mproved insulator showing a conductor wire in operative position. v Figure 2 a side elevation of the same.

States, residing at Figuref3 is an enlarged vertical section through the insulator, showing the method of moving the conductor into a locked position.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the iniproved insulator for supporting the conductor wires B, and including the body C having conductor supporting members D and intermediate locking device E. The means for facilitating the moving of the conductor wire B to locked position is indicatedbythe letter i a a The body C of the insulator is formed of glass or othervitreous material and is substantially conical in configuration and slightly tapered towards its upper end. The lower end of the same is provided with the usual concavity for the reception of the peg 5 carried by the ordinary cross beam of a pole or other support. The body (3 inten mediate its ends is provided with circumferentially extending heads 6 Which strengthen the body and prevents-breaking thereof during the application of the insulator on the supporting peg.

Above the circumferentially extending heads 6 the body (l is providedwith a supporting arrangement D which includes a pair of spaced brackets 7 formed integrally with or iluscd onthe'body. The brackets 7 cxtcnd outwardlyfrom the body C and aw: provided with transversely extending re cesses 8 which have theouter walls there if provided with oppositely directed diagonal slots 9, which communicate with recesses and form means for; placing the line wires B in the recesses. Owing to the opposite inclination of the slots 9', the possibility of accidental displacement of the wires l from the recesses is eliminated. .As stated the brackets 7 are arranged in pairs and when two WlI'eS. are to be supported, a pair of brackets is arranged at each side of the body as clearly shownin Figure 2 with its associated parts E and F. Inasmuch as the,

means for supporting and locking each of the wires B are identically the same in construction, only one of the sup-porting and locking means for one line wire will be described.

The locking means E for the wire B to prevent movement of the same in relation to the brackets include a pair of spaced rack bars 10 having outwardly and downwardly projecting equidistantly spaced teeth it under which the portion of the wire 1 lying between the supporting brackets T is adapted to he slipped. The lower walls of each of the teeth 11 are orovided with arcuate notches l" which form seats tor the wire it so as to prevent accidental displacement of the same trom the teeth.

The means E for 'tacilitatingthe positioning ot' the w re l5 under the teeth ll. oi the rack bars 10 include a plurality of equi-distantly spaced notches 13 arranged in vertical alignment directly between the rack bars. Tl notches 13 each include upwardly and inwardly extending inclined faces 1 and horizontally disposed shouldeis or rests 15, the purpose of which will be hereinafter more tully described. As clearly shown in Figure 3 of the drawings. the shoulders 15 are in substantially direct ailgnnient with the lower faces 12 ot the teeth 11 oi the rack bars.

In operation of the improved insulator the line wire B is first inserted in the recesses 8 formed in the brackets 7 by inturning the wire and inserting the same through the slots 9. After the line wire B has been placed in the supporting brackets. the portion of the same lyingbetween the brackets is bent downwardly under any one of the teeth 11 of the rack bars 10 which may be desired. The positioning ot the wire B under the teeth ll of the rack bars is accomplished by using a scre driver it; or other tool as a lever. and the same is placed over the line wire 13 with its terminal in engagement with the shoulder or rest 15 of one of the notches ill which "forms a iulcrum seat tor the same. -ne tool '16 is then swung downwardly which pushes the wire into position. The outer i'accs of the teeth ll are inclined as at ii so as to facilitate the sliding ot the wire over the same in positioning the wire under the teeth ll. and in the notches 122. The wire 13 may be moved under any one of the teeth ll of the rack bars 10 as may be desired so as to effectively take up the slack in the wire. 7

From the foregoing description it can be seen an improved insulator is provided of: exceptionally durable construction in which he wire can be readily moved into locked position. and when moved into locked position movement thcreo't prevented.

When it is desired to remove the wire from insulator it is merely necessary to bring the tool 16 again into play and position the same in engagement with the wire B and one of the notches l3 and move the tool so as to force the wire out of engagement with the rack bars. after which the wire is removed from the brackets in the ordinary manner.

Changes in details such as reversing the position of the teeth 11 and the notches i may be made without departing from the spirit or scope of. this invention. but;

I claim:

1. An insulator eompris ne' a supporting body having outwardly and longitudinally attending wire sup mrting brackets formed thereon and a rack carried by the support in; body substantially parallel with and intel-mediate said brackets.

2. An insulator comprising a body formed of insulating material, outwardly extending wire supporting brackets carried by the body adjacent to'the upper end thereof and havinn transverse recesses formed therein, theouter wall of the brackets having opposite directed diagonal slots communicating with said apertures, and rack bars arranged between the brackets having the'teeth thereof arranged to selectively receive the part of the wire lying between the braclnsts.

An insulator comprising a body, wire supporting brackets carried by the body having wire receiving openings therein. a rack bar carried by the body intermediate the brackets including av plurality of teeth cooperatively disposed with respect to the openings of said brackets and adapted to se lectively receive the wire which extends be tween said brackets so that said wire may be securely attached to said insulator. and means provided upon said body for receiving a tool to 'lacilitate the placing of a wire upon the teeth oi said rack.

-2t. An insulator comprising a body. spaced wire supporting brackets carried by the body provided with wire receiving recesses therein, and a rack intermediate said bracket having a series of teeth therein tor selectively receiving that portion of a wire ex tending between the brackets.

An insulator comprising a body. a pair of spaced brackets carried by the body. said bracket-s having transverse apertures termed therein, a pair of spaced rack bars formed on the body and arranged intermediate the brackets, and spaced fulcrum notches ar ranged intermediate the brackets.
